What is The Impact of Installing Solar Panels On the House
The impact of solar panels on the roof is mainly due to high installation costs, causing economic burden, long-term wind and sun exposure on the roof, may corrode, electricity consumption will be affected on cloudy days, and holes in the roof during installation may cause roof leakage.
Damage to the roof structure. Solar photovoltaics rely on the volt effect generated by the semiconductors inside the solar panels. If the structure of the roof was not reinforced at the beginning of the design. Because the photovoltaic power generation equipment itself is very heavy, it may damage the roof structure, especially if it is an old house, it is likely to damage the roof.
Destruction of the roof waterproofing. The installation of the bracket of the photovoltaic power generation system needs to be drilled on the roof first, after drilling will destroy the original waterproof layer of the house, if there is no re-do waterproof layer, rain will leak, due to the gap between the screw and the hole, the waterproof process requirements are very high, if too thick will affect the installation. Too thin and ineffective. The effect of the second waterproofing is far less effective than the first, which will increase the possibility of water leakage.
Light pollution problems. If there are relatively tall buildings near the installation of photovoltaic power generation equipment, it is likely to reflect part of the sunlight to the interior of the nearby buildings, causing light pollution to the indoor environment, and relevant studies have shown that excessive light will lead to eye diseases, and even cause anxiety, fatigue, and decreased attention to people's emotions.
Security issues. If it encounters strong winds, the photovoltaic panels are likely to be blown down. In particular, if the battery plate is not firmly installed or the screws are rusted and aged, the battery plate may be blown off by the wind, and the later maintenance cost is also high.
What are the pros and cons of installing solar panels on the roof?
Merit
Solar PV module generation reduces the cost of electricity.
In foreign countries, the installation cost of solar power generation is largely or even completely offset. Instead of waiting to see the savings increase, homeowners can feel the lighter wallet directly. In addition, excess unused solar energy can be stored in the grid.
Solar PV systems require very little maintenance.
Once a solar panel system is set up, perhaps only a few times a year to clean the panels, homeowners can rest assured that the solar panels will generate electricity every day (except in exceptional circumstances).
Malpractices
Solar energy is not fixed.
Solar panels do not have 24-hour sunlight, solar energy cannot be generated at night, and less electricity is generated in winter or in very cloudy and rainy weather.
Solar energy storage is expensive.
While the price of solar modules is falling, batteries and other ways to store excess solar energy are still quite expensive (another reason to stay connected to the grid).
It needs to occupy a certain space.
Generally, the power and area of solar panels are related. The greater the power, the larger the area occupied.
